XVILLIAM F. TODD, OF PONTIAC, MICHIGAN, ASSIGNOR OF ONE-HALF TO EVERETT S. TODD, OF SAME PLACE.

EY E G LA 8 S E S SPECIFICATION forming part of Letters Patent No. 633,670, dated September 26, 1899.

Application filedDecember 15, 1898. Serial No. 699,396. (N0 model) To aZZ whom, it ntcty concern.-

Be it known that 1, WILLIAM F. TODD, a citizen of the United States, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Eyeglasses, of which thefollowingisaspecification,referencebeing had therein to the accompanying drawings.

The invention has reference generally to frameless eyeglasses and spectacles; and it relates particularly to a novel type of fitting for the lens.

The object of my invention is to so construct the fitting that the lens may be fitted to the brace and the parts assembled in their proper relative positions in a more ready and convenient manner than heretofore.

\Vith these objects in View my invention consists in an improved fitting for eyeglasses and spectacles, more fully hereinafter described, and in the novel arrangement and combination of the various parts of the fitting, as shown in the drawings, in which Figure 1 is a perspective View of a pair of eyeglasses with my fitting attached thereto, one lens being detached to more fully illustrate the peculiar construction of the fitting. Fig. 2 is an enlarged detail sectional view of the fitting, showing the same open ready to receive the lens, said figure likewise illustrating a portion of the lens and its securing device. Fig. 3 is a detached front view of a single fitting, showing the same attached to part of a lens, the parts being assembled.

as in use; and Fig. at is a vertical central section taken on line on a; in Fig.

In Fig. 1 the reference-letter A designates the usual spring, B the nose -guard, and O the fitting. The fitting consists of a body D, comprising the stud E and the post F and straps, hereinafter described. The stud is slotted in the usual manner to receive the ends of the spring A and a portion of the nose-guard B, the parts being secured within the stud by means of suitable screws to. Secured to one side of the body and preferably the post is a rigid strap G, provided with a threaded aperture H, adapted to receive a threaded bolt 1. Upon the opposite side of the body and secured thereto in any suitable manner, preferably, when the fitting is to be used in connection with eyeglasses, to the stud, is an inner flexible strap J. This strap is provided with an elongated slot K, adapted to register with the threaded aperture in the rigid strap, the slot being of sufficient length to permit of the flexible strap engaging over the bolt after the latter is screwed entirely within the rigid strap.

L is a nut adapted to engage the portion of the screw which extends beyond the slot, and M is the usual brace for the lens.

It will readily be observed as a result of this construction that after the bolt has been screwed entirely into the rigid strap, so that the head thereof bears against said strap, and the lens fitted over the bolt in its proper position relatively to the brace the final step in assembling the parts-viz., the securing of the flexible strap to the parts already in engagement-may be taken without the necessity of moving the bolt or any of the said parts, whereby a more satisfactory result is obtained.

What I claim as my invention is A fitting for eyeglasses or spectacles, comprising a body, a rigid supporting-strap secured thereto havinga threaded aperture ex tending through its outer end, a threaded bolt engaging the thread within the aperture,

I11 testimony whereof I affiX my signature in presence of two witnesses.
